37 Claims.

This invention relates to apparatus for mechanically applying wrapperbands and/or end caps to rolls of paper or any other material over awide range of diameters and lengths.

An object of the present invention is the provision of means formechanically applying wrapper bands to rolls, such as paper rolls,whereby the latter are uniformly wrapped in a minimum Of time.

Anotherobject is the provision of means for quickly and easily applyingend caps to rolls, such as paper rolls without the necessity of manuallabor other than keeping the apparatus supplied with caps and, ifnecessary, glue.

Under the present generally adopted wrapping procedure, a large sheet ofwrapping paper somewhat longer than the length of the paper roll iswrapped over the entire roll and glued in place.

Due to the wrapper being longer than the roll,

it projects beyond both ends of the roll. A

circular sheet of wrapping paper slightly smaller `in diameter than theroll is placed over the roll end and the projecting ends of the wrapperfolded down over it. `It is then usual to apply by hand glued bands ofwrapping paper around the circumference of the roll at either end whichproject beyond the ends of the roll. The number of bands so appliedvaries with different wrapping requirements and different numbers ofbands may be applied to opposite ends of the same roll. In someinstances one or more bands are wrapped around the circumference of theroll at points `intermediately situated between the two ends.

approximate size of the ends of the roll are covered with glue on oneside and attached to the face of the platens by means of a pin, clip, orother device. Both of these operations are carried out by hand. Theplatens carrying the caps move inwardly and exert pressure on the endsof the roll, and after this pressure has been maintained for apredetermined interval until `the glue has bonded, the platens areretracted and `the roll discharged.

While this machine is particularly designed for After the The roll,lying on handling rolls of paper, and is so described herein, it is tobe understood that it may be used for handling rolls of any othermaterial requiring wrapper bands and/or end caps.

This apparatus is intended to handle paper rolls of varying lengths anddiameters after the main roll wrapping has already been applied in anyconvenient manner. Of course, rolls requiring wrapper bands and/or endcaps and not having the main roll wrapped, may also be handled.

While the machine may be adjusted to handle rolls of different lengths,it usually is set up to handle rolls of a given length in runs orbatches in order to avoid unnecessary waste of time in changing theadjustment of the machine for consecutive rolls of different sizes.

A roll of paper directed to the machine is held until the cycle ofoperation permits it to be moved into position for the first operation.At this time, a band of wrapping paper is applied to either or both endsof the roll and intermediately of the ends, as required. The roll isrotated around its longitudinal axis a pre-determined number of timesfor each band in order to apply the required number of layers of theband. Each end band projects outwardly from its end of the roll. Theroll is then ejected from the wrapper portion of the machine and heldready for the crimping stage.

When the crimper is ready, the roll is moved into position between twocrimper head assemblies which have been moved outwardly away from eachother to enable the roll to be moved into place. The crimpers are thenmoved inwardly against the ends of the roll. Each crimper has aplurality of crimper plates which function somewhat in the same manneras an iris diaphragm. These plates are hingedly mounted on a ring andmay be swung towards and away from the ring centre in substantially thesame vertical plane. When these plates are swung inwardly, they press orcrimp the protruding end of the adjacent wrapper band against lthe endof the roll. Means may be provided for causing the crimper plates tooperate while their head assemblies are still spaced a short distanceaway from the roll end, and after the wrapping bands have been crimped,the assemblies may be moved towards the roll ends to press the foldedbands against the ends of the paper roll, giving them a set.

The roll is now ready to have the caps applied to the ends thereof. Theroll is moved into position between two capper assemblies which havebeen moved outwardly to positions which are spaced from the ends of theroll when the latter is in position between them. The glue is applied toone surface of a cap for each end of the roll, and the cap is moved intoposition against the inner surface of a capper assembly lyingsubstantially parallel with the adjacent roll end. Then the capperassemblies are moved inwardly of the machine until the caps are pressedfirmly against the ends of the roll where they are held for sumcienttime to allow the glue to adhereto the crimped bands on the roll ends.

An example of this invention is illustrated in the accompanyingdrawings, in which,

Figures 1 and 2 constitute a side elevation of the machine from theright to the left thereof, respectively,

Figures 3, 4 andr5 constitute a plan view of the machine from the rightthereof, respectively.

As this machine is particularly designed for handling rolls of Vpaperwhich are very heavy, it is shown in a well lil below the floor levelIl. However, it is to be understood that it may be located on a oor withsuitable means for lifting'the rolls up on to it.

A suitable conveyor i 5, see Figures 1 and 3,

` is provided for moving the paper rolls into position at one end Vofthe machine. Each roll extends longitudinally of the conveyor and it ismoved on to a high end of a sloping deck i8 by any suitable mechanism,such as a hydraulically controlled roll kicker i9, the construction ofwhich is well-known in the paper making industry. The roll moves underthe force of gravity along the deck until it comes to rest upon a rollstop and loader 22. These devices are also well known in the industry,and they consist mainly of a tiltable plate 23 which is normally set atan angle to prevent a paper roll from moving down the deck. When it isdesired to free the roll,

the plate is tilted forwardly by suitable pneufmatic or hydraulic means25, linkage 25 and shaft 25a upon which the plate is mounted, to permit'the roll resting on it to move down the deck. The deck E8 directs eachroll to the band applicator generally designated by the numeral 25,where it comes to rest.

.At this point, it may be stated that when Vthe machine is designed forhandling rolls of diirerent lengths, the remainder of the machine beyondthe band applicator is constructed in two side elements which .may bemoved towards and "away from each other to fit the rolls lof differentsizes. As each side of the machine is a duplicate of the other, only oneside will beV f generally described for the sake of clarity.

Wrapper hemd applicator The applicator '26 appears in Figures 1, 3 and,

. and includes a pair of drums 35 and 3l which extend transversely ofthe machine. These drums lieV in substantially the same horizontal planefand are spaced apart so that when a paper roll moves on to them, itstops moving and is completely supported by them, see Figure 6. Suit- Aroll ejector bar 42 extends transversely of the machine between thedrums 35 and 3| land is normally positioned below the upper surfaces ofthese drums, as clearly shown in Figure 6. The upper surface of theejector bar slopes transversely of the bar so that the rearward edge 43thereof is slightly higher than the forward edge. With this arrangement,the edge 43 of the ejector is located to one side of the vertical planepassing through the centre of the paper roll resting on the drums 39 and3i so that upward movement of the ejector will move said roll over thedrum 3l.

The ejector 42 may be raised and lowered in any desired manner. n thisexampie, hydraulic or pneumatic cylinders i8 are located at oppositesides of the machine and the rams is thereof project upwardly and areconnected to extensions 5E projecting outwardly from the ends of theejector.

rlwo different mechanisms for supplying wrapper bands for the paperrolls are illustrated in the drawings, but it is to be understood thatthese may be interchanged or the same type of mechanism may he used forapplying each band. A carriage is located at -each side of the machinefor holding the mechanism for :supplying the wrapper band to an end ofthe paper roll. Each carriage is mounted on gear wheels 5t running onracks 5? extending transversely of the machine so that the carriage maybe shifted back and forth. The outer gear wheels 55 of the carriage aremounted on a shaft58 which extends from end to end of the carriage,saidshaft having a gear 59 riXedly mountedthereon, `see Figures 1 and 3,which'is rotated'by a pinion Sii mounted on the shaft of an electricmotor'l.

The carriage 55 is provided with means' for mounting one or more paperrolls 65. The'axial length of each roll determines the" Width of thelwrapper band which is applied to the paper roll. A strip of paper fromthe desired roll 55 extends under an idler 67 and up between a feed rollt8 and the drum 3l. This feed roll is Vcarried by supports 69 projectingupwardly. from a glue container It which is pivotally mounted at H onthe carriage 55. The pivot point 'H is located at one edge of the bottomof the glue container, and the ram 12 of a hydraulic cylinder 13 isconnected to the opposite side of said bottom. The lower end ofthecylinder 'i3 is pivotally mounted at l' in the carriage.

and bears against the roll 68.

When the ram 'I2 of the cylinder 'I3 is retracted, the feed roll 68 isspaced from the drum 3l, and when said ram is moved outwardly, thecontainer 'l0 pivots about the point 'il to move the feed roll towardsthe drum, at which time the wrapper band is pressed against said drum.

When it is desired to^feed the wrapper band to the paper roll, the drums30 and 3| are rotated in the direction of the arrows 18. see Figure 6,to turn thel paperroll resting on them. The cylinder 'I3 is operated tocause the feed roll 68 to press the wrapper band against the drum 3l tocause it to move'with the latter. The appli- A glue applicator or rollV'i5 is rotatably mounted in the contaner 75 `paper roll. applicator 92,it receives the glue, and the strip is fcator 16 supplies glue to thesurface of the feed roll which, in turn, applies the glue to the`wrapper band. As the wrapper band passes between the fdrum 3| and thepaper roll, it is pressed on to said roll and the operation continuesuntil the desired number of layers of the wrapper band have been appliedto the roll. then stopped and the ejector 42 is raised to move lthepaper roll over the drum 3| on to the high end of a sloping deck 82located at the discharge iside of the band applicator. -moves on to thisdeck, the paper band at the roll end is servered in any suitable manner,such as -by a serrated cutter 83 located at the end of the The drums 30and 3| are As the paper roll deck facing the drum 3| near each end ofthe latter.

`As stated above, there is a wrapper band feed mechanism at each side ofthe machine. If it is desired to apply a wrapper band to the paper `rollanywhere between the ends thereof, a duplicate I-Iowever, in thisexample, means 4ready described. For this purpose, a carriage 81 may beprovided beneath the deck I8, said carriage being shiftable laterally ofthe machine in 4the same manner as the carriage 55. The carriage 81 isadapted to support a roll of wrapper band stock 89. A strip from thisroll extends under lan idler roll 9| and over a glue applicator 92rotatably mounted in a glue container 93, said container being pivotallymounted on the carriage at 94, see Figure 6. The paper strip continuesover a nned feed roll 95 also carried by `the container 93, and aroundthe drum 3D. The

ram 95 of a pneumatic or hydraulic cylinder 91 Yis connected to thecontainer beneath the feed roll and is adapted to move said rolltowardsand away from the drum 39. When the latter drum 'isrotated andthe feed roll presses the strip of paper against it, the wrapper band isfed to the As the paper strip 'moves over the pressed against the paperroll by the drum. A suitable cutter, such as a serrated cutter 98, ex-

tends along the ejector 42 at the edge 43 thereof "and facing the drum3| so that when the ejector is operated to move the roll on to the deck8,2,

the wrapper band is cut off by the cutter as the "roll moves towards thedeck.

With this applicator, the paper bands may be applied to either or bothends of the paper roll and to any portion thereof between said ends. Ifit is desired, the number of layers of the band Vwrappers may be thesame or different at each position. For example, the paper roll mayrequire 7 thicknesses of the wrapper band at one end, 5 thicknesses atthe other, and 4 in the middle. in this case, the band applicator drumsare started and the band material fed to one end of the paper rollthereon only. When the paper roll has made -hold more than one paperroll at a time. In any= same time.

case, a roll stop and loader |02 similar to the 4stop and loader 22 isprovided adjacent the end of this deck remote from the band applicator.This device retains the paper rolls on the deck until one is requiredfor the next operation.

Band crimper assembly This assembly, see Figures 2, 4, 7 and 8, has acombined stop and unloader I D located centrally thereof so that a paperroll resting on it is centred on a transverse centre line or axis of theassembly, see Figure 4. This stop and loader may be the same as the stopand loaders 22 and |82, although the one shown in the drawings isslightly diierent since it is intended to carry the full load of thepaper rolls. This device includes a pair of dished supports ||4 whichare pivotally mounted at one end at ||5. The opposite ends of thesesupports are carried by a horizontal shaft 6 which is pivotally mountedin and carried by the upper end of the ram ||1 of a hydraulicorpneumatic cylinder H8. Normally the ends of i the supports `carried bythe ram are lower than their opposite ends so that a paper roll fromdeck 82 may move on to but not past this device. When it is desired tounload the roll, the cylinder is operated to move its ram outwardly andraise the adjacent ends of the supports to tip the paper roll off thedevice.

A crimper is located at each side of the machine, and as these areidentical, only one will be described in detail. The crimper cons-istsof a relatively long air or hydraulic cylinder |25 having a piston rod|25` extending towards the centre of the machine on the centre lineofthe 'crimper assembly. A vertical base plate |21 is mounted on theouter end of the piston rod, said base plate being larger than the endof the largest paper roll to be handled by this apparatus. This baseplate has wheels |28 riding on tracks |29 which extend across themachine.

A large gear |34 is rotatably mounted on the piston rod |23 against theouter surface of the bas-e plate. A plurality of pinions |35 arearranged around and mesh with the large gear. Each of these pinions ismounted on a short shaft 33 which extends through the plate |21 and is`journalled in a bearing |31 supported by and pro- 'jecting inwardlyfrom the plate.

A crimper plate |40 is mounted on the inner end of each shaft |36. Eachcrimper plate may be of any desired shape and it is mounted adjacent oneend thereof on its shaft. These crimper plates are arranged in a circlearound the axis and normally are swung outwardly from said axis, asshown in Figures 2 and 7. Suitable means is provided for rotating thegear |34 to swing the `crimper plates inwardly towards said axis. `This`operated to move one rod inwardly and the other outwardly, the pinionsconnected to the levers |41 are rotated, thus causing the large gear |34to move so that all pinions are rotated at the This swings the crimperplates inwardly or outwardly depending upon the direction of movement ofthe gear.

A'|54 is mounted on the inner surface of the base plate |21centrallyfthereoi and has .a piston rod |55 V`,projecting inwardly ofthe machine, upon the free end of which is mounted a bumper plate |56.The piston rod |55 is normally extended and the bumper plate |56 lies ina plane slightly closer to the centre of th-e machine than the plane ofthe crimper plates hill as clearly shown in 'Figure 4. When the rod |55is retracted, the bumper |5615 withdrawn `toY the outer side of `theplane of the crimper plates.

flren the .cylinders |25 are operated to move the crimper assembliestowards the ends of the paper .'roll. It will be noted that the bearings|31 are arranged on the base plate |21 so that they clear Vthetperipheryof the largest roll to be handled :by the machine. Acontacts the rollend, the movement of the When the bumper plate |56 crimper assemblies isstopped. The vertical plane yofthese plates is spaced a little from theroll end,

VThe .unloader Hi) is operated to direct the paper lroll on to the highend of a sloping deck |62 vwhich directs the roll to the end capapplicator.

Capper l l-The deckV |62 directs each paper roll onto a combination stopand unloader |65 mounted beneath the transverse centre line |66 of thecapper assembly shown in Figures 2, 5, 9 and 10. This device is similarto the combination stop and unloader H of the crimper assembly.

Suitable means is provided for applying glue toone surface of caps |69,moving these caps :into position and then applying them to the oppositeends of a paper roll on the stop and unloader |65. For paper rolls, thecaps |69 are round and .of approximately the same diameter as the roll.

Astack of these caps is maintained in a rack |12 Each rack is located toone side of the centre line |66 of the capper, as clearly shown inFigure 5, and is mounted Yonta carriage |13 having wheels |14 ridingontracks which extend longitudinally .of the machine, `One or moreflexible suction pipes |13 extend from vacuum apparatus. .not shown, andeach has a nozzle |19 which :is .dirrected towards and rests upon theuppermost cap near the edge thereof closest to the centre line |66. Eachnozzle is supported by a cross bar |82 which is carried at its oppositeends by aV pair of substantially horizontal arms |83 Whichare pivotallymounted on a shaft |64 whichisfsupported by brackets |65 extendingupwardly -from the rack. Cam discs |86 are mounted near :and below thearms |83 eccentrically on a common shaft V|89 which has a sprocket |90mounted on one end thereof connected by chain 9| to 1another sprocket|92 mounted on a shaft |93 of Yan electric motor |94. Each arm has aroller |96 mounted thereon immediately above one ofthe cams |98 so thatwhen the latter is rotated, it swings the arm upwardly. Each nozzle .|19extends to and is secured to a coupling 266 which is carried by andfixed to the cross bar |.82,.and the latter rotatable in bearings 29| onthe ends or the arms |83. A pair of L-shaped supports 295 having theupper ends of their Vertical sections iixedly secured to the bar |82 at206, see Figures 5 and 9, carry a. transverse shaft 269. at the outerends of their horizontal sections. vA roller 2id is mounted on each endof this shaft beneath a substantially horizontal cam track '2|\|.

With this arrangement, each time the inner ends of the arms |83 areraised by the cams |88, the rollers 2|@ move in a horizontal directionbeneath the cam tracks 2 causing the VLeshaped supports 205 to rotatethe cross bar-|52 atthis time. The nozzles |19 are lifted by thisactionand the rotation of the cross bar `causes the lower ends of thesenozzles to swing towards the centre line of the capper |66. Suction inthe pipe or pipes |15 causes the nozzles to lift the uppermost cap |59and the swinging movement of the nozzles moves the edge of saidcap intothe nip between two feed rolls 2|5 locatedfadjacent said nozzles. Theuppermost roll is rotated by the shaft |93 of the motor |915 and pressesagainst the lower roll. These rolls move the cap over a table 2|5 to aglue applicator 2|1. Normally when applying glue to a surface of anarticle, the article is moved between a pressure roller and a glueapplicator roller. However, in this case, each cap |69 is circular inshape so that vfor a'large percentage of thetime the pressure rollerwill be bearing against the glue v'applicator .roller and would becomecovered withglue in a having aplurality of spaced grooves 22| formedinthe periphery thereof. This roller rotates in a container 222 whichholds a quantity of glue. Thepressure roller is in the form of aplurality of spaced discs `225 mounted on a shaft 226, 'each disc beinglocated above a groove 22| in the roller 220, see 1Figures 5 and 10.There Yis suiiicient space between the discs and the periphery of theroller to enable a cap to pass therebetween. A notched scraper 228 hasiingers 229 fitting into the grooves 22| to keep the latter cleared ofglue. The main portion of the scraper' controls the thickness or" thelayer of glue on the periphery of the applicator roller. The Vdisc shaft225 is rotated in any convenient manner. In this eriample, a sprocket232 mounted on one end of the shaft |93 on which the upper pressure roll2|5 Ais mounted, is connected by a chain 234 to the adjacent end of theroll 220, see Figure 5, so that the latter roll rotateswith the pressureroll discs 225.

A cap passing between the roller 220 and the. discs 225 has a coating ofglue applied to its lower surface, excepting the portions thereofpassing over the roller grooves. Each cap is received by a series ofrolls 240, each of which consists of a plurality of spaced discs 24|mounted on a shaft 242. Each of these shafts has a sprocket 243connected by a common chain 244 to a single sprocket 245 mounted on theshaft 238. The discs 24| are in line with the grooves 22| 0f theapplicator roll 226, so that the portions of the lower surfaces of eachcap which are devoid of glue come into contact with said discs. Ifdesired, suitable Scrapers may be provided for removing any glue whichmay adhere to the discs. A plurality of fingers 248 project upwardlyadjacent the edge of the table formed by the discs 24| remote from theglue applicator.

It will be noted that all the mechanism described so far for handlingthe caps |69 is mountedon the carriage |13. Suitable means illustratedat 255 is provided for shifting the carriage longitudinally of themachine. The reason for this is that it is necessary to have the centreof each cap resting on the discs 24| lying in the vertical plane of thecentre line |66 of the capper. Ascaps of different sizes are used inthis machine, the carriage |13 is shifted lon` gitudinally` ofthemachine to position the different sized caps in the right place. i

A relatively long air or hydraulic cylinder 265 is mounted on the outerside of each table made up of discs 24| and on the centre line |66of thecapper. A piston rod 266 extends inwardly from the cylinder towards thecentre of the machine and has a vertical platen 261 mounted on its innerend. This platen is larger than the end of the largest roll to behandled by the machine, and it has wheels 268 riding on transversetracks 269 so that the platen may be moved towards and away from` thecentre of the machine by the piston rod. i

`A hollow., arm 214, see Figures 9 and. l0, is mounted in the platen andhas its face iiush with the inner face 215 of the latter. A plurality ofopenings 216 are formed in the inner face of the hollow arm 214. Thisarm is carried by levers 219 at its lower end which are pivotallymounted on a shaft 280 carried by bracket 28| extending downwardlyfromthe platen. The opposite end` of one of these levers is connected to thepiston rod 284 of an air or hydraulic cylinder 285 pivotally mounted onthe back of the platen by means of a bracket 286. The arm 214 normallylies within the platen in a substantially vertical plane, and when thepiston rod 284 is retracted, i

this arm is moved into a substantially horizontal position, as shown indotted lines in Figure l0, immediately above the discs 24|. Actually, atthis time, the hollow arm engages a cap |69 resting `onsaid discs. Asuction hose 290 is connected to the bottom of the arm 214,.,said hoseextending to suitable vacuum apparatus, not shown.

In operation, the cams |88 raisethe arms` |83 tolft the uppermost cap|69 `from the pile and insert the` edge thereof between the pressurerollers `2|5. These move the cap to the glue applicator, and the powerdriven discs 225 and roll; 220 thereof move the cap with` its layer ofglue on tothe table of discs 24|, the pins 248 stoppingthe cap in thecorrect position. When a roll of paper reaches the stop and uploader|65, the platens 261 are drawn outwardly as far as possible. Thecylinders 285 of the platens are actuated to cause the hollow arms 214to move clown on to the caps in position on the table discs in front ofthem. When these arms are returned to their normal vertical positions,the suction therein lifts the caps with them. Then the cylinders 265 areactuated to move the platens inwardly against the ends oi the paper rollto press the caps against the crimped wrapper band. Pressure ismaintained long enough to ensure the caps remaining in place, and thenthe platens are withdrawn to their outermost positions. The unloader |65is then actuated to direct the paper roll on to the upper end of asloping deck 29| which guides it away from the machine.

Controls and general operation In order to co-ordinate all the componentparts of this machine, a system of inter-locking controis is installed.These controls are all standard equipment and need not be described indetail herein. It has been found that the band application is theslowest operation so that all other parts of the equipment are timedfrom the band applicator. The number of revolutions made by the paperroll when the band o1' bands are being put on and the length of time theroll remains in this section of the machine may be controlled by anoperator. However, the operation of the remainder oi the machine will becompletely automatic. Paper rolls are supplied to the machine by theconveyor I5. At the right time, the roll kicker le is operated tomoveeach roli on to the sloping deck I8. The stop 22 holds the roll onthe deck until the band applicator is ready to receive it. Then theloader 22 is operated to free the roll to allow it to move on to thedrums 66 and 3i of the band applicator. At this point, the requiredbands are applied to the roll at either or both ends and/or any desiredpoint between said ends. When this is completed, the ejector i2 isoperated to move the roll on to the sloping deck 82 where it is retainedby the stop |02.

When the loader |62 moves a paper roll on to the stop H6 of the crimper,cylinders |25 are actuated to move the crimper assemblies towards theroll ends, and the central cylinders |54 are operated to extend thebumper plates |56 beyond the planes of the crimper plates. As soon asthe bumper plates engage the ends of the roll, the crimper plates areswung inwardly to crimp the wrapper bands over the roll ends. Then thebumper plates |56 are withdrawn to permit the crimper plates to pressagainst and set the crimped bands. As the crimper assemblies arewithdrawn from the roll, the crimper plates are returned to theiroutermost positions. The unloader H6 discharges the roll from thecrimper and said roil moves down the deck |62 on to the stop |65. Justprior to this, caps had been moved through the glue applicator andpicked up by hollow arms 214 of the platens 261, the latter being intheir outermost positions. The cylinders 265 are actuated to move theplatens against the roll ends. The suction is cut off from the hollowarms and, after a predetermined time, the platens are withdrawn to theiroutermost positions, by which time new caps are resting on the tables ofdiscs 24|. The unloader |65 is now raised to discharge the roll on todeck 29| and out of the machine.
